Application filed July 9,' 1927. Serial No. 204543.

This inventionrelates to drainage fittings and the object oi theinvention is to provide a floor drain arranged so that seepage throughthe floor is carried into the drain tlms'prcventing any leakage betweenfloors.

Another objectof the invention is to provide a floor drain in whichthelead flashing is carried into the drain and .caulked in place so thatany see-page through the floor or about the drain is carriedin-t-o thedrain'outlet.

A further obj ect of the invention is to provide a flanged member havingcorrugations on the under surface thereon through which seepage is"adapted to flow, apertures being provided through which the seepage maypass into thedrain outlet.

- These objects and the several novel features of the invention "arehereinafter more .l'ul-ly described and claimed and the pre-' terred*form oil? construction by which these objects are attained 'iSshOWH inthe accompanying drawing in -Which Fig. 1 is a. section through a 'floordrain embodying my invention.

Fig. 2 is a perspective View or the drain with the lead flashingremoved.

Fig. is a perspective view of the-corrugated plate which is positionedon the lead flashing.

The drain comprises a cup shaped member 1 having an outwardly extendingflange 3. The member 1 is provided with a shoulder 5 and an annular'm'em-berfl is positioned on this shoulder as shown in Fig. 1. The mem-I her 6 is provided with an inwardly extend ing threaded flange 7 and aseries of apertures 8 are provided through this flange as shown. Athreaded sleeve 9 is threaded into the flange 7 and is provided with anenlarged upper end which is closed by the perforated plate 10. A plate11 is threaded onto the sleeve 9 and a seepage ring 12 is positionedabout the periphery of the plate 11. This drainage fitting is to be usedfor a drain in floors through whichseepage may occur such as a concretefloor in a shower bath or like construction. To prevent the seepage frompassing through the floor a lead plate 13 is provided which extendsoutwardly to the edge of the floor. This plate is formed from sheet leadwhich is carried in over the flange 3 and downwardly into the space 14between the member 6 and the wall of the cup shaped member 1. This space14 is then filled with caulking in the ill thereof. This plate 11 isthreaded tlQWIl- Wardly 'on the sleeve 9 to secure the lead platebetween the "flange 3 and the member 11. /Vhen the concrete floor islaid the parts are in the position shown in Fig. 1. Should any o1v thewater pass through the concrete floor or through cracks in the floor itpasses over the lead plate 13 and through theseepage ring 12 and throughthe corrugations in the plate 11 and thence through the apertures 8 inthe member 6 into the drain. By this arrangement the Water is preventedfrom passing througl'i to the floor below and all of the water whichseeps through the floor is carried into the drain. For this purpose theedge of the "lead sheet or flashing is carried upwardly slightly abovethe floor level at the outer edges oil the floor.

From the foregoing description it becomes evident that the device isvery simple and efficient "in operation; will not easily get out oforder; will carry all seepage through the floor back into 'the drain,and "provides a device which accomplishes the objects described.

Having thus fully described my invention, its utility and mode ofoperatioIn-what 1 claim and desire to secure by Letters Patlar memberand the lead flashing being filled with caulking to the top of theannular member a tubular member, a plate threaded onto under surface,the tubular member being threaded into the flange of the annular memherto bring the plate into contact with the lead flashing and a seepagering positioned on the lead flashing about the periphery of the tubularmember and having a corrugated threaded flange provided with a seriesthe space between the annular member and flashing being filled withcaulking to the top of the annular member, a tubular member threadedinto the flange of the annular member and having a drain plate at theupper end, a plate threaded onto the-tubular member and having a corruated under surface resting on the lead flashing and a seepageringpositioned about the periphery ofthe said plate. u p

3. A dramage fitting comprising a cup shaped Inember'having anannular-shoulder,

' an annular member positioned on thesaid shoulder and having aninwardly extending apertures therethrough, alead flashing .extendinginto the cup shaped member between the annular memberand the wall of thecup shaped member, a tubular member threaded into the flange of theannular member, a

plate threaded ontojthe tubular member and having aradially corrugatedunder surface adapted to rest on the lead flashing and a seepage ring1positionedabout the periphery of the said p ate.

4. In adrainage fitting, a cup shaped memher having a peripheral flangeat the upper edge and an annular shoulder adjacentthe bottom,an annularmember positioned on the shoulder, and having an inwardly exteiidingthreaded flange provided with a series of apertures therethrough, atubular member threaded into. the saidflange and formed at the upper endto provide a drainage inlet, a plate threaded ontothe: tubular memberand provided with a corru ated under surface and a seepageringpositioned about the periphery of said plate.

5. In a drainage fitting, a cup shapedmemher having an annular shoulder,an annular member positioned on the shoulder and having an inwardlyextending threaded flange provided with a series of aperturestherethrough, a tubular member threaded into the said flange, a platethreaded onthe tubular member and having acorrugated under surface and aseepage ring positioned about the periphery of the said plate, the upperend of the tubular member beingformed to provide a drainage inlet.

6. Ina drainage'fitting,a cup shaped meme.

her having a peripheral flange, an annular member supported thereby andhaving an inwardly extending threaded flange provided with a series ofapertures therethrough a tubular member threaded into the flange, a-

plate threaded on the tubular member and contiguous to. said peripheralflange, said plate having a corrugatedunder surface pro- 'Vldlllgdrainage grooves, thepsa d structure being adapted to bepositioned in afloor of self-hardening plastic material,and porous materialsopositionedrelatlve to the plate as to )revent the plastic' materialpassing throng the draina e grooves, the upper end of the tubular mem erbeing formed to provide the drainage inlet. v u
